The anti🚫-derailment🚃 & thread🧵 hijackingšŸ”« thread🧵 ⁉

Nice I never saw that thread. The titan will be very useful as it’s not a basic shape :ok_hand:

Pretty basic as a CAD

especially when amal posted the dimensions on the webpage

didn’t take me long at all

I meant one of the standard ones you get in a game engine without modeling them, box, capsule, sphere, cylinder.

Ah, gotcha

Are there any specific file formats you can import?

here’s a post with some file extensions examples from SolidWorks

Usually I work with .fbx but I have blender so I should be able to either convert or copy them if needed.
I’m not too deep into cad, usually I use tinkercad for 3D printing.

Everyone wants to use metric… until it matters :wink:

Can a thermal camera make out implants? Maybe after applying ice? My guess is the implant would take longer to warm up than the surrounding tissue since there’s no fluid flowing in it. Maybe it’s not noticable :thinking:

I doubt it. But x series implants will show up on a vein viewer.

In theory Since glass is has worse thermal properties than flesh, so there would be a point heating or cooling the area where the glass is at a different temperature?

But thermal also usually only sees surface last I checked… so even if your implant was 2 degrees warmer or colder than surrounding skin… it would need to effect the surface temp? Which probably takes more energy than the minimal difference in temperature?

Yeah you can definitely feel it during the winter with close to freezing temperatures. There’s a lingering cold spot where the glassies are as soon as you get in a warmer environment. I think other forum members mentioned that too. I bet it’s even more noticeable with magnets since they are a nice solid chunk of metal but I don’t remember if that was the case for me.

This is an xG3 from months ago. Installed bevel up because I was to busy filming to notice the installer was doing it that way.
Any way see the black spot ? It’s been there almost since the beginning. It’s under the skin and won’t budge no matter how much I torture it. :sweat_smile: I’m pretty sure it’s one of those skin flaps, stuck in there and slowly being destroyed. It will go away eventually but I’m impatient !
Anyone have one?

The discoloration is likely because blood got trapped between two pieces of skin. It will go away but it’ll take a long time.

Your question made me curious so I did a few tests:

1 Hand at ā€œroomā€ temperature.


While I was moving the camera around to take this image I was able to convince myself that at certain angles I could make out a vaguely cooler blob but I think it was just a combination of wishful thinking and knowing where the chip is.

2 Cooled the area around the chip with ice


The chip (a 2x12mm NTAG216) is pretty much in the centre of the darkest blue area

3 Warmed the surface with water.


I used warm water because it conducts heat so efficiently that I thought that gave me the best chance of rapidly heating just the surface.

Objectively, despite occasionally deciding that maybe I could see a very slight difference, I think this shows that heat cameras don’t reveal chips. Partly because, as Erequiet said, the reading is superficial so the chip would have to cool down the skin above it to show up and partly because I think that chips are so small and so completely enveloped in the skin around them that they probably cool/heat at almost exactly the same speed as their surroundings.

I’m glad someone tried :grin:
Did you keep looking as the cold one warmed back up? Also maybe something like an xG3 would be more noticeable?
Also big flexes. They create a barrier between the skin and the rest of the body :thinking:

Do you know if a 20 buck IR flashlight type will work?

Or does it have to be a professional job for a couple of grand?

I watched the whole thing because the viewfinder of the camera shows you in real time.

Something with a bigger mass to warm up may work better but I think that a barrier with the skin is actually counter-productive because to show up the object has to cool down the skin above it.

A bit like the fact that the light from a blinky is mostly the light that is diffused by the skin above it.

You can use visible light if you’re patient and have done some photography before. It’s cheap depending on what you already have :sweat_smile:

Cool. Loved the visible light ā€œX-Rayā€ machine!

Id love to hear it :grin:

I dropped the idea of teh V1 as sensing isnt gonna happen in that location, but a second V2 would be extremely useful …

Ive done some testing with a small neodymium magnet ā€œabout the size of the G3ā€ and 1in seam a hair too close … but there is absolutely no attraction at 1.25" to 1.5" …
